    Guys just got an IHI at bargain price, need a manifold to fit it, I know its an old aged question, but would it be easier to get on custom made???

    Or are there any suppliers you guys have used and would recommend???

    nice one

    b5 chassis? no manifolds exist. any IHI manis in the UK are for A3 platform VAg transverse cars and will have you turbo upside down with the exhaust pointing forward.
    just had some flanges cut and am about to have one welded up. 316 stainless steels tubular runners, equal length, mounted turbo on top....couls have another made up if you are interested.

    BTW ....how much did you pay for the IHI? VF34?

    VF34 was standard on STI from 200 IIRC.

    check out the following link

    [​IMG]
    316 grade 1.5" OD Stainless tubing, I am also toying with the idea of larger tubing (around 1.75") but the smaller tubing will make it spool up lower down the range and I am not looking for nutty power. Just 350ish.... [;)]

    [​IMG]
    10mm laser cut 304 stainless flanges for head, turbo and exhaust.

    Bends and pipes work will be about £80, welding I expect to be around £150 and the flanges were £100.
    All in I hope to have it done for around £300-350
    will look something like this:

    [​IMG]
    That is a "Full Race" mani (robotically tig welded) retails at over $1000.
    Not planning on the wastegate tube for the obvious reason

    will let you know how I get on.

    IHI should easily see you over 300... I ran an IHI in my corrado and that made 340 only limited by the fuel pump not quite being strong enough.

    it'll do over 400 if you want it to! few people have problems with really tuned IHI's over 330-350bhp, they melt as well so I am told!
    but I am sticking with 1.5" OD mani tubing to get the spool up earlier at the expense of top end flow and big numbers.
    It's going on a new 2l bottom eventually so it should nice and torquey off boost

    Sounds good I'm only looking for 300 tops my missus drives the car too, with our little un in.

    Where did you get the flanges cut??

    there is a guy in our town who builds custom exhausts, he's really good, If I can ge tthe templates I can possibly get him to build some.
